FloWizard
‹ Our first general purpose CFD
product for non-specialists driven by
FLUENT and Gambit .
‹ FloWizard’s focus is on ease of use
and automation:
z It is a highly-automated, “first pass”
simulation tool for use in basic flow
and heat transfer calculations.
z A Wizard-based interface guides the
user through all the steps of a CFD
analysis, from problem set-up to post-
processing.
z The user is insulated from specialized
CFD parameters, such as
discretization and turbulence model
choices.
